A710E High Strength Steel Plate
WixSteel Industrial can offer SpartanTM high strength (to over 100 ksi (690 MPa) minimum yield strength), high toughness, improved weldability steels as alternatives to traditional quenched and tem- pered alloy steels. The SpartanTM family of steels are low carbon; copper precipitation hardened steels based upon the original efforts that led to the development of ASTM A710 Grade A. Spartan steels can be produced to meet the requirements of the existing ASTM.
A710 Grade A and A736 Grade A specifications and Navy Specification MIL-S-24645A, now covered under NAVSEA Technical Publica- tion T9074-BD-GIB-010/0300 (HSLA-80 and HSLA-100), as well as unique customer speci cations in a variety of strength and toughness levels.
Because of their improved weldability, ArcelorMittal’s SpartanTM steels have been used to replace traditional high strength alloy steels (ASTM A514 and A543) in a number of applications. These include U.S. Navy aircraft carriers, cruisers and submarines, as well as mining and dredging equipment, high reliability lifting hardware, offshore drilling platforms, large valves and heavy duty truck frames. The Spartan V chemistry is being considered for bridge applications where it is known as ASTM A709 HPS 100W.
